Re: Evinrude 9.9 water in cylinder 1999 4-stroke
Wow thats still a baby for a outboard very new . I would never think that anything that new would have problems . Check your water pump too . I bet she had overheat when you last had her out on the water . It may as well be a bad head gasket from age . How offen do you run the motor what kind of use is on her .But boobie is right get the factory manual from evinrude .4 CYCLE is different than the older 2 cycle engines . You need to pump oil of some sort for lube for the crank and conecting rod bearing . 4 cycle will work just like a car in some sort but the only differents is your pumping water from the lake . You need to check where the water came from in the first place . Did you over heat it last time out on the water ?. You know I bet the casting for the block is aluminum casting . Make sure your block did'nt crack too. check for a warped head with a strait edge , I think you can use a feller gage to check for the proper gap under it . The factory manual should tell you the measurement you need . check yuor spark plug too , but you placed a gage for compression on it . what did you get in the good cylinder and the bad cylinder had no compression right .
